Forge Spring Tuning Kit for Turbo Actuators

Now you can fine tune your turbo actuator to the exact needs of your engine with this complete tuning kit. In the valve tuning kit you will find four springs and the associated spring retainer. The strongest spring is the red, followed by blue, yellow and green which is the weakest.

Forge actuators are normally supplied with, unless otherwise specified, a spring that will match the tension of the manufacturer’s original fitment valve. However, as many owners undertaking performance modifications some may wish to re-tune the actuator characteristics to suit a given application.

Please note that serious or even fatal damage may occur to the engine and associated components if this product is incorrectly matched to the individual engine requirements. Owen Developments and Forge Motorsport cannot assume any responsibility for any adverse effects resulting from the installation of this product.

When ordering, please specify if you require this kit for a piston or a diaphragm actuator.

These kits are not suitable for Forge’s diesel actuator for Garrett VNT turbos.
